Definitions

  • ABSTRACT non-metallic cord ply having the cords thereof oriented at a 0 angle to the median equatorial plane of the tire is superposed on a plural-layer ply structure of metallic wires or strips which in each layer are crossed relative to those in the adjacent layer and are oriented at a bias angle, preferably between 16 and 30, to the plane.
  • the layers of non-metallic cord ply structure are of equal width and are symmetrical with respect to the median equatorial plane.
  • the plural-layer nonmetallic cord ply structure is constituted by a single length of breaker cord wound in a continuous spiral circumferentially of the carcass for at least a plurality of full turns.
  • the layers of the metallic ply structure may be of equal or unequal widths, and arranged symmetrically or asymmetrically with respect to median equatorial plane of the plural-layer nonmetallic ply structure. Where the layers of the metallic ply structure have unequal widths, the widest ply may be either radially outward or radially inward of the other ply or plies.
  • the width of the non-metallic ply structure ranges from 30mm more to 30mm less than the width of the widest ply layer of the metallic ply structure.
  • the widest ply layer of the metallic ply structure is symmetrical with respect to the median equatorial plane and the non-metallic ply structure.
  • This invention relates to an improved belt or breaker for pneumatic tires having a radial carcass or a substantially radial carcass.
  • the belts or breakers which are part of the construction of pneumatic tires are designed to counteract the forces of internal pressure to which they are subjected, as well as forces such as tensions or compressions of dynamic origin, and to counteract the deformations to which they are subjected in service, under the influence, for example, of accelerations or decelerations of the vehicle, centrifugal forces when turning, or high speeds in a straight line.
  • the construction of the belt or breaker must therefore be such that it will withstand in an optimum manner, the effects of these various forces.
  • the belt or breaker, especially for radial ply carcass tires are composed of superposed mutually crossed rubberized plies of parallel essentially inextensible textile cords or steel cables or strips of steel or monofilaments.
  • the textile breaker plies insure a resistance to stretching and compression along the parallels to the equatorial plane of the tire carcass, while the metal plies insure resistance to stretching and compression along the directions perpendicular to the equatorial plane, that is to say along the meridians of the casing.
  • a more particular object of the present invention is I a novel and improved belted pneumatic tire with a breaker constructed to provide desirable qualities of road holding ability, driving comfort, lightness in weight, high speed capability and high wear resistance.
  • the present invention is a belted tire in which the tread-reinforcing belt or breaker interposed between the carcass and the tread is characterized by the combination of a first plural-layer metallic ply structure of at least two metal plies and a second plural-layer ply structure of at least two non-metallic plies of equal width superposed on the first ply structure.
  • the reinforcing elements of the first ply structure are parallel to each other and oriented at a bias angle to the equatorial plane of the tire carcass at an angle between 16 and 30.
  • the second ply structure is disposed symmetrically with respect to the median equatorial plane.
  • the non-metallic reinforcing elements of the second ply structure are parallel to the median equatorial plane and are preferably made of a heatshrinking material.
  • the second ply structure is a single length of breaker cord of appropriate width wound in a continuous spiral circumferentially of the tire carcass for a plurality of full turns and preferably for an additional small fraction of the next full turn.
  • the width of the non-metallic ply structure is such that each remote lateral edge is within an interval 60mm wide, the center of which interval is determined by the corresponding remote lateral edge of the widest metal ply.
  • the ply layers of the metal ply structure can be of equal or unequal widths and the structure can be arranged symmetrically or asymmetrically to the median equatorial plane and the non-metallic ply structure. Where the widths are unequal, either the radially inwardmost or the radially outwardmost ply can be the widest ply. Further where the widths are unequal, the remote lateral edges of two adjacent plies can correspond and the other remote lateral edges can be offset from each other. The widest ply of the metal ply structure is symmetrical with respect to the median equatorial plane and the non-metallic ply structure.

  • the tire 11 comprises, for example, a radial or substantially radial ply carcass 12, which may be either a single-ply or a plural-ply structure and the reinforcing element of which may be cords or cables of such materials as rayon, nylon, polyester, glass fiber, steel wire or the like.
  • the tire l1 further includes sidewalls l3 and 14 overlying the respective lateral regions of the carcass and terminating at their radially inwardmost edges in a pair of beads 15 and 16.
  • a tread l7 overlies the crown region of the carcass and adjoining the sidewalls l3 and 14 at their radially outwardmost regions, i.e.
  • the marginal regions of the carcass ply or plies 12 are turned up about the beads 15 and 16, as shown at 12a and 12b.
  • the present invention directed to the construction of the breaker, is applicable as well to belted tires having non-radial or bias ply carcass constructions in which the cords are oriented at bias angles below
  • a tire having a carcass construction in which the cords of each body ply are radial or substantially radial in orientation, i.e. disposed in planes oriented substantially normal to the plane of the beads and to the crown centerline or median equatorial plane XX of the tire has a relatively high bias angle of about 80 to 90.
  • the breaker 20 according to the basic principles of the invention and according to one embodiment thereof comprises two distinct ply structures 21 and 22 arranged in superposed relation to each other circumferentially of the carcass 12 and generally symmetrical with respect to the median equatorial plane XX of the tire 11.
  • the first ply structure 21 is shown as a plural-layer arrangement of two plies or layers 23 and 24 of rubberized parallel metallic, preferably steel, reinforcing elements 23a and 24a which may be either lamelliform, i.e. in the form of flat strips or bands with rounded edges, or filiform, i.e., in the form of generally round wires or cables.
  • the elements 23a and 24a are generally symmetrically oriented at respective equal but opposite substantial bias angles a and a to the median equatorial plane XX.
  • the bias angle (1 and a is approximately 16 to 30 to the median equatorial plane and the reinforcing elements from one ply to the next adjacent ply may or may not symmetrically intersect one another.
  • the second ply structure 22 is shown as a plural-layer arrangement of two plies or layers 25 and 26 of rubberized parallel breaker cords or cables 27 and 27a of non-metallic textile material such as rayon, glass fiber, nylon, polyester and the like, oriented as an essentially angle, i.e., parallel, to the equatorial plane XX.
  • the plies 23 and 24 can be either of unequal widths, as shown in FIGS. 1 to 9 or of equal widths, as shown in FIGS. 10 and 11. Where the plies 23 and 24 are of unequal widths, the inner ply 23 can be greater in width than the outer ply 24, or the ply 23 can be lesser in width than the ply 24.
  • the two ply structures 21 and 22 can be superposed symmetrically with respect to the median equatorial plane XX of the carcass, as shown in FIGS. 1 and 1A, 2, 3, 6, 7, l0 and 11. The two ply structures 21 and 22 may also be superposed asymmetrically with respect to the median equatorial plane XX, as shown in FIGS. 4, 5, 8 and 9. In FIGS.
  • the ply structure 21 is displaced laterally to one side of the median equatorial plane such that plies 23 and 24 are of equal width on that side, whereas on the other side, the plies 23 and 24 are of unequal widths. It is within the contemplation of the present invention that the asymmetric arrangement can be on either lateral side of the median equatorial plane. As shown in FIGS. 4 and 9 the inner ply 23 can have a greater width than the outer ply 24, or as shown in FIGS. 5 and 8, the inner ply 23 can have a lesser width than the outer ply 24.
  • the terms inner ply and outer ply refer to a radial section of the tire when viewed from the carcass to the tread.
  • the widest ply layer of the metal ply structure is symmetrical with respect to the median equatorial plane and the non-metallic ply structure.
  • plies 25 and 26 forming ply structure 22 are of equal widths and are superposed symmetrically with respect to the median equatorial plane XX.
  • the total width W of the ply structure 22 can be greater or less than the total width W of the ply structure 21. In either instance, the total width W, is between a minimum width W and a maximum W such that:
  • the width W is therefore:
  • the distance L between the lateral edges of the two ply structures, on either side of the plane, is determined by A: (W -W From the above equations, the maximum distance is therefore 30mm.
  • FIG. 10 shows the ply structure 22 of width W, which is of the maximum width W and, therefore extends 30mm beyond each lateral edge of the ply structure 21.
  • FIG. 11 shows the ply structure 22 of width W which is the minimum width W,,, and therefore the lateral edges of plies 25 and 26 are 30 mm. inward of the lateral edges of ply structure 21.
  • the distance L is the amount of overlapping relationship between the first and second ply structures. It is determined by a measurement between the remote lateral edge of the widest ply of the first ply structure and the remote lateral edge of the second ply structure when measured on the same side of the median equatorial plane. Stated in another manner, the remote lateral edges of the second ply structure is within an interval 60mm wide, the center of which interval is determined by the corresponding remote lateral edge of the ply of the first ply structure which is farthest from the median equatorial plane.
  • the width of the non-metallic second ply structure ranges from 30mm more to 30mm less than the width of the widest ply-layer of the metal first ply structure, where this widest ply-layer is symmetrical with respect to the median equatorial plane and the second ply structure.
  • the breaker utilizes lamelliform metallic reinforcing elements
  • these will generally be in the form of thin flat metal, preferably steel, strips or bands having a thickness between about 0.12 and 0.40mm, preferably on the order of about 0.25mm, and a width between about 1 and 3mm, and the lateral spacing of adjacent strips or bands in any given layer of the ply structure will be between about 0.5 and lmm.
  • the breaker utilizes filiform metallic reinforcing elements
  • these will generally be in the form of round metal, preferably steel, wires or cables having an effective diameter between about 0.25 and 2.5mm, and the lateral spacing of adjacent wires or cables in the ply structure will be between about 0.5 and 1.0 times the said diameter. It is within the contemplation of the present invention that either type of metallic reinforcing elements may be used in both plies of the ply structure 30, or that one ply may include lamelliform elements and the other filiform elements.
  • the ply structure 22 is constituted by a single length of weftless 0 breaker cord fabric, in which all the cords extend substantially parallel to the longitudinal dimension of the fabric, wound in a continuous spiral circumferentially about the crown region of the carcass 12 for at least a plural number of full turns (FIG. 12) equal to the number of layers desired, two in the breaker construction according to the present invention shown in the drawings.
  • the length of the cord fabric is wound in a continuous spiral circumferentially of the tire carcass for somewhat more than the requisite number of full turns, i.e.
  • the plural plies resulting from spiral winding are of equal widths and are disposed symmetrically with respect to the equatorial plane X-)(.
  • the reinforcing elements of the plural plies are cords or filaments made of a synthetic'or natural textile materials and are oriented parallel to the equatorial plane of the carcass.
  • the synthetic or natural textile material may be cotton, rayon, nylon or a polyester.
  • a synthetic textile material such as rayon, nylon or a polyester, is desirable since these materials are heat shrinkable during vulcanization of the tire carcass.
  • the heatshrinkable textile materials will provide a restraint against the stretching of the underlying metal plies caused by centrifuge forces during high speed service.
  • Shrinking of the textile ply material although ordinarily an undesirable feature, provides a prestressing of the breaker which counteracts expansion forces during tire service.
  • the number of metal plies comprising ply structure 21 may vary according to the service of the tire. In the present invention, two metal plies are shown. Where the tire is intended for heavy service, as, for example, in large vehicles, off-the-road or farm use, the number of metal plies can be greater than two.
  • the relative arrangement of the metal plies is in accordance with the general principles of the present invention. Thus, where the metal plies are arranged as in FIGS. 2 and 7, the successive plies have widths which decrease when viewed in a direction radially from the carcass to the tread. Where the metal plies correspond to the arrangement of FIGS. 3 and 6, the successive plies have widths which increase when viewed in a direction radially from the carcass to the tread.
  • the successive plies have widths which decrease, while in FIGS. 5 and 8, the successive plies have widths which increase, when either arrangement is viewed in a direction radially from the carcass to the tread.
  • Pneumatic tires having a radial or substantially radial carcass and a tread reinforcing breaker according to the present invention have improved operating characteristics.
  • Three tire carcasses were vulcanized in a mold 625mm in diameter.
  • a first tire carcass included a breaker comprising only two metal plies, such as the ply-layers used in ply structure 21 of the present invention. After vulcanization, the tire, when inflated, had a diameter of 626mm.
  • a third tire carcass included a breaker comprising a first metal two-ply structure and a superposed second non-metal two-ply structure according to the present invention, the reinforcing elements being made of polyester. After vul
  • the tire when inflated, had a diameter of 625mm.
  • a comparison of the mold diameter and the inflated diameter indicates the tensile condition of the breaker.
  • the diameter difference of lmm larger shows the restraining effect of the metal breaker plies.
  • the diameter difference is significant and shows that the textile breaker plies are under tension due to shrinking during vulcanization.
  • there is no diameter difference showing the desirable advantage of a textile and metal breaker. Since the textile part of the breaker shrinks during vulcanization, this ply structure is under tension.
  • a breaker comprising only plural metal ply-layers in which the metal reinforcing elements are oriented at a bias to the median equatorial plane of the tire at an approximate angle of 30, provides a tire having comfort able riding characteristics. Because of this bias angle, the lateral rigidity of the tire is lower, and the cornering and road holding characteristics are correspondingly lower.
  • the addition of plural textile ply-layers in accordance with the present invention does not affect the comfortable riding characteristics, but considerably improves the cornering and road holding characteristics.
  • the breaker according to the present invention permits the tire to be lighter in weight and therefore provide a more comfortable riding tire.
  • the reduction in weight is due to the use of a textile instead of only metal reinforcing breaker elements.
  • the density of the reinforcing elements of the plural metal ply'layers can be reduced because the plural textile ply-layers provide additional tread reinforcement.
  • a pneumatic tire having a carcass, the tread being integral with the carcass a tread surrounding the crown region of such carcass, sidewalls overlying the lateral regions of the carcass from the bead regions of the tire to the marginal regions of the tread, and a tread reinforcing breaker disposed circumferentially about the crown region of the carcass between the latter and the tread, the breaker comprising a first plural-layer ply structure having elongated metallic reinforcing elements and a second plural-layer ply structure having elongated parallel non-metallic reinforcing elements, the second ply structure being arranged in superposed concentric relation to the first ply structure, the metallic reinforcing elements in each layer of the first ply structure being oriented at a respective bias angle of between 16 and 30 to the median equatorial plane of the tire and in crossing relation to the metallic reinforcing elements in each adjacent layer of the first ply structure, the layers of the second ply structure being of equal width and symmetrical
